Sanders’ Magic Number: 70

We were going to start doing a state-by-state countdown to make it clearer when it was mathematically impossible for Donald Trump to clear the 1,237 delegates he needs to clinch or where Bernie Sanders might overtake Hillary Clinton in pledged delegates. Turns out, Ted Cruz is right: “California will decide“. There’s simply too many delegates there; as unlikely as it might be, if Trump or Sanders win 100% of the vote there, they win.

A lot of folks are talking about how Sanders needs to win 57% or more of the remaining delegates to tie. That number doesn’t incorporate the polling that shows her with 10-point leads in New York, Maryland, Pennsylvania, and California (there is polling for New Jersey, but it’s really old).

Using a very simple model that assumes a Clinton “ceiling” (i.e. all undecideds go to Bernie, so if Clinton is polling under 50 percent as she is in California, Sanders actually wins) using the current poll averages, Sanders would need to pull in 70 percent of the vote in all other jurisdictions to pull ahead of Clinton by June 14.

Based on past results, that seems doable in Oregon, but unlikely in, say, Puerto Rico (which has basically the same number of delegates).

Later this week, we’ll add calculations to show how much of each vote the candidates need in each state to hit their targets, but with the states with polling representing around 70 percent of the outstanding delegates, Sanders must lower Clinton’s ceiling substantially in New York, Maryland, and Pennsylvania to have a realistic shot of catching her.
